FAQs

Yes. A batch-matched certificate of analysis is published for every batch, showing purity by HPLC, identity by mass spectrometry, appearance and the release date for that specific lot. Certificates can be viewed and downloaded from the Certificate of Analysis section for each peptide.

Match the batch code printed on the vial label to the batch number on the certificate. If the two do not match, stop and contact us before beginning any work.

Yes. Batches are tested by an independent third-party laboratory in addition to in-house analysis, so the purity and identity figures on the certificate are not self-reported alone.

Bacteriostatic water is the standard diluent for laboratory reconstitution. Add it slowly against the inside wall of the vial and swirl gently rather than shaking, which can shear the peptide.

There is no single correct volume — the amount of water added determines the concentration of the resulting solution and therefore the volume drawn for any given quantity. Two millilitres is a common choice because it makes the arithmetic straightforward. Our reconstitution calculator works the figures out for you.

Gloves, eye protection and a laboratory coat, with handling carried out on a clean, dedicated surface. Dispose of vials and sharps through your facility's standard laboratory waste route.

Orders are accepted from qualified research professionals and laboratory facilities. By placing an order you confirm the material will be used solely for in-vitro or preclinical research in an appropriate laboratory setting.

Purchasing is restricted to research use. You are agreeing at checkout that the material is intended for laboratory research only, and that it will not be used in humans or animals.

Yes. Discounts are applied automatically at the basket: 2.5% on two vials, 5% on three, and 10% on five or more of the same product.

Major credit and debit cards are accepted at checkout, along with Apple Pay and Google Pay, and an instant automated bank transfer option.

Yes. Payments are processed using industry-standard encryption and security measures, and card details are never stored on our systems.

Because of the nature of these products and the storage conditions required to maintain their quality, we cannot accept returns or exchanges. All sales are final. If an order arrives damaged, contact us within 48 hours and we will resolve it.

Contact us before ordering and we will confirm which batches are currently in stock so you can keep a study on a single lot.

Peptides are short chains of amino acids linked by peptide bonds — the same building blocks that make up proteins, on a smaller scale. In the body they act as signalling molecules, which is why synthetic peptides are widely used in laboratory research to study defined biological pathways.

Every peptide we supply is manufactured to ≥99% purity as measured by HPLC, with identity confirmed by mass spectrometry. The figures for your specific batch appear on the certificate of analysis published on this website.

No. All products are supplied strictly for laboratory research use. They are not for human or veterinary consumption, and not for diagnostic or therapeutic use of any kind.

Peptides are supplied as a sterile lyophilised (freeze-dried) powder in a sealed vial, which keeps the sequence stable in transit and allows the receiving laboratory to reconstitute at its own working concentration.

No. All peptides ship in lyophilised powder form so the shelf life of the material stays at its maximum. Bacteriostatic water is required to reconstitute the powder in the laboratory.

Bacteriostatic water is not included with a peptide order and is purchased separately. Our 10 ml bacteriostatic mixing water is listed in the catalogue alongside the peptide range.

No. Under our research-only terms we cannot provide any dosage guidance, protocols or suggestions of use. Material is supplied for laboratory research, and the purchaser is responsible for how it is used within that research setting.

Stock levels shown on the site are live, so anything marked out of stock is currently unavailable to ship. Restocks typically arrive within 7 to 10 working days. Where we do not intend to restock a product, it is removed from the catalogue entirely.

Orders placed before the daily cut-off ship the same working day on a free tracked 3–5 day service covering Dublin, Cork, Galway, Limerick, Waterford and the rest of Ireland.

Yes. European and international research orders can be arranged — contact us with the destination before ordering and we will confirm the service and transit time available to your facility.

Tracking details are emailed as soon as the parcel leaves us, and can be used to follow the delivery through to your facility.

Yes. Parcels are dispatched in plain outer packaging with no product description shown on the label.

Lyophilised peptides are stable at ambient temperature for the duration of a short tracked transit, so cold chain packaging is not required for domestic delivery. Refrigerate on arrival.

Confirm the vial seal is intact, the powder cake looks white and undisturbed, and the batch code on the label matches the certificate of analysis published on this website.

Contact our support team within 48 hours of delivery. Keep the packaging and vials as received, and send photographs along with the batch code so we can trace it against the production record and resolve it quickly.

Store sealed lyophilised vials at −20 °C or lower for long-term storage, in a sealed container with a desiccant to absorb moisture. Refrigeration at 2–8 °C is suitable for shorter periods. Keep vials away from light.

Once reconstituted, keep the solution refrigerated at 2–8 °C and protected from light, and treat it as a short-lived working stock. Avoid repeated freeze-thaw cycles, which degrade peptide integrity.

Lyophilised peptide is hygroscopic. Opening a cold vial lets condensation form on the powder, which starts the degradation that cold storage is there to prevent. Allow around 20 minutes at room temperature before breaking the seal.
